' Application filed. February 1, 192s. Serial No. 85,103.

My invention relates to furring strips, and more particularly to strips of this character particularly adapted for use with metallic fireproof wall and ceiling constructions;

A furring strip embodying my invention is so constructed that it may readily be secured by means of nails to Wooden studding, or by means of expansion or toggle bolts, to wall or ceiling blocks, and permit the me- 1 0 tallic wall or ceiling covering to be secured thereto by means of nails, notwithstanding that the furring is essentiallya sheet metal product, and that the nails for securing the wall or ceiling sheet metal are engageable therewith only at separated or isolated points.

In furring strips embodying my invention nail blocks or studs are used which are so constructed as to be adjustable with relation to the portion of the furring strip supporting same, thus permitting their location upon the strips with regard to the desired positioning of nails securing the metal wall or ceiling sheets in place, and not to the building construction itself,

, Said nail blocks or studshave dimensions, and are .so constructed, that no great accuracy is required as to their location, a sufficient contact area between same and the wall or ceiling sheets being afforded to en sure the engagement of a nail therewith, even though there be considerable inaccuracy in the locating of the nail blocks or studs.

The nail blocks or studs themselves while r relying upon compressible material embodied in the structure thereof for holding the nails,

are of themselves of a fireproof construction. While the nail blocks or studs are movable in relation to the portions of the furring strip supporting same, the construction is such as to ensure a. sufliciently rigid support for said blocks or studs to permit nails to, be readily driven within the block or stud.

The construction of the blocks or studs and the manner of mountlng same are such as to afford an area of supports for theunetal ceiling or wall sheets, which will prevent deformation of such sheets as a result of blows upon the nails securing them in position, all blocks or studs carried by each strip, and the strips themselves, ensuring the plates or sheets being located with their faces in sufficiently accurate alinement to ensure the desired flatness of thesheets secured thereto. Irregularity inthe walls or ceilings of a building structure will be at least partially compensated for, by furring strips of my invention.

j The invention consists primarily in a furring strip embodying therein a channelled strip adaptedto be secured in relation to a building structure, a plurality of blocks each having a metal sheathing completely inclosing a compressible body, and cooperating means upon said channelled strip and upon said blocks, whereby said blocks are supported in relationto, and-adjustable longitudinally of, said channelled strip; and i and combination of parts as are hereinafter set forth and described, and'more particularly pointed out in the claims hereto appendedf 7' Referring to the drawings, I Fig. l is an elevation of a section 1 of furring strip embodying my invention;

Fig. 2 is a section on the line 22 of Fig. 1, showing the furring strip attached to a ceiling beam; and

in such other novel features of construction Fig.3 isa detail view of the stud or block 7 removed from the channelled strip by which it is secured in relation to the building structure. I v

Like letters refer to like parts throughout the several views. p

In the embodimentofmy invention shown in the drawings, a furring strip is'illustrated which includes therein a channelled strip a having mounted therein a plurality of nail blocks or studs .7). Said strip a is preferably provided with a neck 0, and an enlarged angularhead d, affording upon opposite sides of the neck 0, bearing seats d for the block or stud b. The seats d and the depth of the metal in the neck 0 will afford a. sufiiciently rigid backing for the blocks or studs-b to resist the force of blows applied to the block while driving a nail tnereinto. The dimensions ofeach bloelt or such as to have a snug sliding fit between the side walls of the head (Z.

The edges of the channelled strip a are bent inwardl T as at e.e and have rectan u- D larly formed edges or rims fwhich are adapted to enter channels adjacent opposite sides of the blocks or studs Z) for the purpose of preventing the expansion of a block as a resultof blows thereon, or the loosening of the co-operating means for securing said blocks or studs in position in relation to said btrips due to movement'ofthe sides of thehead (Z in relation to said blocks or studs.

The blocks or studs proper comprise a core 9 preferably of compressed asbestos or other fibrous material and aninclosing'metallic casing consisting of a cupped base hportionz" will project slightly beyond the channelled strip and afford a bearing area ,adaptedto be engaged bythe metal of the ceiling or wall sheets which will resist deformation of these sheets, while at the same time compensating for any slight inaccuracy in the positioning of the. various blocks or studs with relation to the point upon, the sheets where the nail is to be driven.

The channelled piece a is made ofv fairly light sheet metal stock which may be readily penetratedor pierced byan ordinarynail.

The material used for the sheathing of the nail block or stud is also. made of light metal stock which may be readily penetrated or pierced by the type of nail commonly used for securing the metal ceiling or wall sheets in position.

lVhile, as stated, the core of each nail block or stud may be made of compressed asbestos or other fibrous mater al, t may, 1': desired, also be made ofwood since the metal sheathing inclosing this core will prevent the combustion of the core in the event of fire, even though it maybe made of wood. \Vooden core, metal sheathed constructions are commonly used in certain types of fireproof structures and have been found highly efiicient.

The bent or, formed edges ee and .f f of the channelled strip and the channels and raised edge portions IP" of the blocks or studs b constituting interlocking members firmly holding the blocks in relationto the channel furring strips, and'prevent the spreading of the sides of the channel as a result of blows upon said blocks or studs.

In addition to'affording a non-combustible or fireproof support for the metal sheets of the wall or ceiling finish, the furring strip of my invention spaces said sheets, in their entirety, away from the building studding or ceiling beams so that in the event that said studding or beams are of wood, additional fire protection is afforded by the air space between; said sheets and said studding or beams.

The. formation of the neck 0 of the channelled strips a, when the strips are assembled in a building, positions the means securing these strips out of engaging relation with the blocks or studs Z) By increasing or decreasing the length of this neck any desired spacing of the metal sheets of the wall or ceiling finish with relation to the building structure, may be secured, while permitting the use of blocks or studs Z) of uniform dimensions irrespective of variation in the depth of the neck 0 of different strips a.

In the accompanying drawings short nails are indicated as the securing means between the metal sheets of'the wall or ceiling finish and the blocks or studs 12. If, however, it is desired to lock these blocks or studs with relation to the channel or the building structure, long nails may be used which will pass through the cupped topv '2', the cupped base It and the channel a.

In the use of furring strips embodying my invention, channelled strips a arecfirst secured to the studding or the building block structure of the walls-or the ceiling of a room by means of nails in the first instance, or by means of expansion bolts in the event ofsolid walls, or by toggle bolts in-the event of hollow tile walls. Thesestrips are positioned at approximately the desired distance apart. a

i The various blocks or studs are mounted in relation to the strips either before or after they are connected with the wall or ceiling structure, it being possible to shiftthese blocks if they are in a position to interfere with the mounting ofthe' strip a. A plurality of parallel strips, or course, are used and they may be run in any directiondesired. The channel-form of the strip and the holding of the side webs thereof by the blocks 6, imparts rigidity tothese strips so that even if they are run, transversely to the ceiling beam or studding, the blocks 7) may be placed without'regard to the point of at tachment of the strips to the building structure.

Blocks or studs Z) of a number required bythe desired spacing of the points of connection of the metallic ceiling or wall sheets with the furring strips are mountedin each channeled strip, and after the strips, are p0 possible, however, to have a variation of onehalfof an inch, ormore, in one direction or the other along thestrip a, since the exposed face of each block or stud E) has suflicient area to receive and firmly hold nails within this range. is permitted as, to the positioning of the parallel furring strips. This condition perits accuracy in'the placing of nails, as to the wall or ceiling sheets, without requiring corresponding accuracy as to the furring strips. v j

As a nail is driveirinto the block or stud, it will penetrate and pass through the eX- posed face of the cupped topi and into the fillerg, the expansioirof this filler after compression by the nail, talring a firm grip upon the nail and thus firmly holding it.

Blows upon the nail are transmitted to i the block or stud Z2 and therethrough to the seats (1 upon which the block or stud Z) rests. These shocks are transmitted through the sidewalls of the neck 0 to the beam, studding or wall structure with which the channeled strip a is connected, By reason of the interlocking members e-e, ff, j 7" and /b7c upon the channeled strip a, and the blocks or studs Z), the force of such blows cannot spread the sides of thechanvneled strip. These interlocking members also prevent spreading of the filler g. Hence the blocks or studs Z) will always. be frictionally held inposition by the channeled strip a although as stated, if desired long nails may be used which in addition to penetrating the block or stud, will pass through the bottom thereof and through the bottom of'the channeled strip. a

,A furring strip embodying my invention possesses simplicity of construction, and convenience ofvinstallation, being capable of use without requiring any extreme accuracy in the relation of parts. The nails may be driven perfectly straighter at an angle as desired, but under all circun'istances an adequateholding of the nail is assured.

A furring strip'embodying the invention may also be inexpensively produced, since its construction is such as to permit the use of fairly light sheet metal,

It is not my intention to limit the invention to the precise, details of construction shown in the accompanying drawings, it being apparent that such may be varied without departing from the spirit and scope of the invention. I
